An MS student in the lab, Gloria Angima, is conducting research on the effects of galactooligosaccharides or lactose supplementation on lactose intolerance. Gloria is mentored by Drs. Dave Dallas and Si Hong Park.
The goal of this study is to determine whether prebiotics can modulate the human gut microbiome resulting in alleviation of lactose intolerance symptoms.
The study consists of a one-week screening period, 4 weeks of a supplementation period, and a 4-week washout period (total 9 weeks).
During the supplementation period, subjects will be randomly assigned to consume GOS or lactose daily for 4 weeks.
● Stool samples will be collected weekly
● Stool samples will be collected at home by subjects
Inclusion criteria:
